Many imaging technologies and their contrast agents  chemicals used during scans to help detect tumors and other problems  involve exposure to radiation or heavy metals, which present potential health risks to ...

(Phys.org)—Given that blood supply to the brain and spinal cord is fundamental to central nervous system (CNS) physiology and pathology, it's not surprising that trauma and disease in spinal cord blood ...

One of the ways in which cancer cells evade anticancer therapy is by producing a protein that pumps drugs out of the cell before these compounds can exert their cell-killing effects. A research team at Northwestern University ...

(PhysOrg.com) -- Swapping the chemical groups that originally coat iron oxide nanoparticles and making the particles soluble in biological solvents shows great promise for medical applications, such as drug delivery and contrast ...

A team of researchers, led by scientists at Case Western Reserve University, has developed a multifunctional nanoparticle that enables magnetic resonance imaging (MRI) to pinpoint blood vessel plaques caused by atherosclerosis. ...

Researchers at Harvard-affiliated McLean Hospital have shown a new category of "green" nanoparticles comprised of a non-toxic, protein-based nanotechnology that can non-invasively cross the blood brain barrier and is capable ...

(PhysOrg.com) -- Nanoparticles play a significant role in the development of future diagnostic and therapeutic techniques for tumors, for example as transporters for drugs or as contrast agents. Absorption ...
